WARP-MEASURING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 681,157, dated August 20, 1901.

i 1 Application filed October 4, 1900. Serial No. 32,034 (No model.)

To all whom it mmy concern:

Be it known that I, GEORGE W. WALKER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Warp-Measurin g Machines,

I of whichthe following is a specification.

a My lnvention consists of certain improvements in measuring devices particularly adapted formeasuring warp during its passage from the yarn-spools to the warping-mill.

My invention is fully illustrated in the accompanying drawings, in which'- Figure 1 is a side elevation of my improved measuring device, with the standard for supporting the same partially broken away.

a Fig. 2 is an end elevation of said measuring device, and Fig. 3 is a plan view of the same. The object of my invention is to determine I accurately theamount of warp passed onto the warping-mill and to subdivide the same into cuts or sections more readily than heretofore. y the warp for apredetermined length of cloth.

By out I mean that portion of y a 1 is the measuring-roll over which the warp or passes, directed thereto by the guide or tension roller 2. In the machine which I t have devised four times the circumference of 1 the measuringroll represents a yard, so that the warp in its passage across this roll may be definitely measured into the desired length For the purpose of 1 indicating the number of yards and to sound an alarm when a certain number of yards have been measured the following mechanism is employed:

On the end of the spindle 3 of the roller 1 a worm 4; is arranged, meshing with a wormf wheel 5, carried by a short shaft 6, mounted in the frame 7. Mounted on the end of the short shaft 6 is achain-wheel 8, moving with 1 y the worm-wheel and carrying a chain 9. Carried by a spindle is a toothed wheel 11, said wheel being mounted above a chainwheel 8 and having a dial on its face. This wheel is adapted to be engaged by a pin 12 of the chain 9, so as to be moved forward the 1 distance of one tooth every time the pin 12 a of the chain 9 comes in contact with said teeth. As I have arranged this mechanism everyfour revolutions of the worm moves the worm-wheel 5 and the chain-wheel 8 the distance of one link of the chain 9, representing one yard of warp, so that by arranging a link for every yard of the warp-cut to be measured said out may be accurately measured in lengths of any size, the number of links of the chain corresponding to the number of yards in the cut. The chain illustrated in the drawings forming part of this application has fifteen links, and consequently every fifteen yards of the warp measured, representing a cut, will be registered by the dial and the gong sounded at the same time. A pointer 13 is fixed to the end of the spindle 10, and as the wheel 11 moves when engaged by the pin 12 of the chain 9 a new figure on the dial will be brought opposite said pointer. To prevent the toothed dial moving more than the distance of one tooth, a spring catch or pawl 14, having a suitable depression, is carried by the frame and adapted to engage a tooth of this wheel as the latter is moved by the pinon the chain, so that there is no danger of the chain-wheel moving more than a single tooth and no danger of its accidental movement.

The chain 9 which I employ is made up of detachable links, and I can put in or remove as many links as desired, so as to increase or decrease the number of yards to be measured for each cut or section of warp.

As soon as a certain length of warp las been measured oif, such length being determined by the number of links in the chain, and before it is indicated by the dial, desire to announce such fact by the ringing ofa gong.

Carried by a suitable stud 15, secured to an arm projecting upwardly at one side of the frame, is a gong 16, and I arrange a hammer 17, adapted to strike this gong at proper intervals by suitable mechanism, which operates as follows: On the spindle 10 of the toothed dial-wheel 11 is a loose sleeve 18, having a depending arm 19 and having at the rear a flattened portion 20, arranged at an angle to the perpendicular. The supporting wire or stem 21 of the hammer 17 terminates in a coiled spring .22, which is secured to a pin 23, mounted on the frame, and said spring tends to hold said hammer in the position shown in Fig. 1, with the stem of the same lying across the angular face of the jflattened portion of the sleeve 18. Oneof the links of the chain 9 has a projection 24,

which is immediately in advance of the link 1 having the pin 12. The movement of the worm-wheel 5 carries the chain-wheel 8 and chain 9 around until the projection 24 of the latter is in position to engage the depending arm 19 of the sleeve 18 and hold the hammer 17 out of engagement with the gong 16 until the chain-wheel is moved to the extent of another link, when the projection 24 will be latter, or fromlany'other cause, it may be necessary to pull the warp back through the measuring device, the mechanism will act in the reverse direction and indicate the amount of warp pulled back. For this purpose the depending arm 19 of the sleeve 18 'is permitted toswing in both directions, so that it may be acted "upon by the projection 24, and when the warp begins to run on the mill again there will be no mistake made in the length run on, due to the retraction of any portion of the warp.

Although not entirely necessary, I prefer to use the tension-roller 2 when running the warp onto the measuring-r0111, as said roller 2 will tend to give the warp more surface on said measuring-roll; but it is desirable that, this tension-roller be moved out of the Way when the warp is retracted to tie any broken 5 threads, and for this purpose the roller 2 is carried by arms 25, pivoted to the frame 7. Set-screws 26 are carried by said arms, the bolt portion of which screws is adapted to semicircular slots 27 in the frame 7, whereby said arms may be securely held when the tension-roller is moved to a position such as shown, for instance, in dotted lines in Fig. 2. Although I have described my invention as i applied to the measuring of warp, and particularly for the purpose of dividing such warp into cuts in its passage from yarn-spools to the warping-mill, I desire it to be under- Y stood that my inventioncovers also the measuring of cloth, cord, or any other materialf adapted to pass over a draftroller which serves to operate the measuring mechanism.
